Stewart Audio

Updating Dante Firmware

Audinate released new firmware for the Ultimo (UXT and ULT)and Brooklyn II ICs in late 2017. These add in support for AES67 in the case of the Ultimo UXT ICs, and support for Dante Domain Manager in all ICs. (There is no AES67 support for the Ultino ULT ICs.)

To update the firmware in your Dante-enabled Stewart Audio product, you will need to know which IC is used.

    All MC850 Series products (MC850-LZ-D, MC850-VC-D, MC850-MXZ-D) use the Brooklyn II IC.
    All PoE amplifiers (AV8-2-LZ-D, CVA16-1-LZ-D, AV20-2-LZ-D, and CVA40-1-CV-D) use the Ultimo UXT IC.
    The FLX and DSP100 series amplifiers, and the Netamps can use either the ULT or UXT IC. To determine the IC used in your product, open Dante Controller and double-click on the device in question. This will open a Device View window for that device. Click on the Status tab and consult the Dante Information section. The Model and Dante firmware version is listed. If the firmware version listed is the current version, no further work is required. Your device is up to date. Otherwise, the Ultimo ULT ICs are denoted by Ultimo2 or Ultimo4. The UXT ICs are denoted by UltimoX2 or UltimoX4. With this information you can select the .dnt file appropriate for your Stewart Audio amplifier model and IC type. To update your Dante-enabled Stewart Audio product to the most recent firmware version, follow the instructions below.
